When Vanessa Traina arrived at Le Caprice for a dinner celebrating her new capsule collection for French label Maje on Wednesday, she was putting the wares to good use. Wearing a cut-out heavy top that stood in opposition to the sleet storm outside, the socialite had draped a tuxedo jacket from the line over her shoulders.

“I have another one that goes over when I go outside,” she said of the coat, laughing. Traina and her sister Victoria have been known to pal around with a certain set of buzzed-about young designers, and, sure enough, a few had shown up for support. Alexander Wang was there, as were Jack McCollough and Lazaro Hernandez of Proenza Schouler, and Joseph Altuzarra. Mary-Kate and Ashley Olsen didn’t make it to dinner, but they’d stopped by Barneys New York for the presentation beforehand.
